exception "No compatible MPEG-4 encoder found" raised when codec is mp4

Mpeg4VideoEncoderVcm class uses MPEG-4 encoders installed in the system. So, to be able to do MPEG-4 encoding, you should install either of the codecs listed in docs

Hi @baSSiLL I downloaded the encoder you mentioned in the documentation but I am still receiving this exception. Any ideas why that might be? Great library btw!

Hi @therealsquidgee
Probably mismatching bitness between codec and program. For instance, you've installed 32-bit codec only and run your program as 64-bit process.
What does Mpeg4VideoEncoderVcm.GetAvailableCodecs return?

Hi baSSiLL,

Same issue here on Windows 7 (64b). I've installed x264vfw for 32 and 64. A GetAvailableCodecs returns:

x264vfw - H.264/MPEG-4 AVC codec

But i get:

Unhandled Exception: System.InvalidOperationException: Encoder operation returned an error: -100.
at SharpAvi.Codecs.Mpeg4VideoEncoderVcm.CheckICResult(Int32 result)

I compiled it in 32/64 with the same result. By the way, it works on W10...

Hi @husk3rdu
Sorry for a late reply. Do you have any news about your issue?
Is there any additional info about error in x264 log window?
Did you try different versions of x264vfw?
